Quick answer

Hand wash the 12oz. Chill Sleeve in cool water with a drop of mild soap, rinse well, and air dry it completely before storing it loosely. Avoid hot water, machine washing, and wringing, which can distort the insulated neoprene.

Why neoprene needs a gentler routine than the bottle

The Chill Sleeve is made of insulated neoprene contoured to hug the ergonomic shape of the 12oz Cirkul bottle. That material is what keeps your drink chilled and your hands dry, but it is also the part most easily damaged by heat and stretching. A dishwasher cycle or a hot-water soak can break down the insulation and change the fit, so treat the sleeve differently from a stainless steel bottle.

When to wash and when to just air it out

You do not need to wash the sleeve after every fill. If it only held a closed bottle and stayed dry, airing it out is enough. Wash it when you notice sweat residue, spills, or a stale smell, or after a workout or commute where the sleeve absorbed moisture. Overwashing speeds up wear, so aim for a quick hand wash every week or two with spot rinses in between.

Step-by-step Chill Sleeve cleaning and storage

  1. Empty and rinse: Slide the sleeve off the bottle and turn it inside out. Rinse both sides under cool running water to remove loose residue. Checkpoint: if the sleeve still holds a strong odor after rinsing, continue to the soap wash instead of skipping it.
  2. Hand wash with mild soap: Add a drop of gentle dish soap to a bowl of cool water. Squeeze the sleeve gently in the water for about 30 seconds, then rinse until the water runs clear. Common mistake: using hot water or strong cleaners, which can degrade the neoprene and leave a lingering smell.
  3. Press, do not wring: Lay the sleeve flat on a clean towel and press down with another towel to absorb excess water. Never twist or wring it. Checkpoint: the sleeve should still hold its contoured shape; if it looks stretched, reshape it gently while damp.
  4. Air dry fully: Leave the sleeve inside out in a well-ventilated spot away from direct sun and heat until it is completely dry inside and out. Common mistake: storing it damp, which traps moisture and can cause a musty smell.
  5. Store loosely: Once dry, store the sleeve flat or loosely rolled in a drawer or cabinet. Do not fold it tightly or stack heavy items on top. Checkpoint: keep it away from sharp objects and heat sources that could puncture or warp the neoprene.
